Ok, this is wierd. I was using an old v1.3 Gameshark disc as my original. My son has all the others in his room. Anyway, before modding it booted. After modding with the chip enabled, it booted. With the chip disabled, it didnt boot. So I go get v1.93 game shark. With chip disabled, it boots. Star wars original - boots, Sprint car original - boots, just not that v1.3 game shark.
Now if anyone can explain why, I would love to hear it.
Anyway, the moral to this story is that the 3.1 works just fine and I have a cruddy original here I was trying.
